Reconstitution GuideUnderstanding Units
The calculator tells you how many units to draw. Here's exactly what a unit is — and why it's the same on every insulin syringe.
1 unit = 0.01 mL
On a standard U-100 insulin syringe, every unit is one-hundredth of a millilitre. So 10 units = 0.1 mL and 100 units = 1 mL. "Units" are just an easy way to read very small volumes.
A unit is always the same
It doesn't matter which insulin syringe you grab — a unit is always 0.01 mL. Drawing "20 units" pulls the exact same amount of liquid (0.2 mL) on a 0.3 mL, 0.5 mL, or 1 mL syringe.
Syringes hold different totals
Insulin syringes come in different capacities — they simply fit a different number of units. The tick marks stay 0.01 mL apart; bigger syringes just have more of them.
Example: a 20-unit dose = 0.2 mL — the same on all three syringes above. The only difference is how much empty space is left over.
